Calculate EDD and POG of LMP 12 april 2026
LMP: 12 April 2026
EDD (Naegele's Rule): Add 1 year, subtract 3 months, add 7 days to LMP.
- 12 April → subtract 3 months = 12 January → add 7 days = 19 January 2027
POG (Period of Gestation): Today is 11 July 2026.
- From 12 April 2026 to 11 July 2026 = 12 weeks and 6 days (approximately 13 weeks)
Here are the precise calculations:
EDD - Expected Date of Delivery
Using Naegele's Rule: LMP + 9 months + 7 days (or +1 year - 3 months + 7 days)
| Step | Calculation |
|---|---|
| LMP | 12 April 2026 |
| +1 year | 12 April 2027 |
| -3 months | 12 January 2027 |
| +7 days | 19 January 2027 |
EDD = 19 January 2027
POG - Period of Gestation (as of today, 11 July 2026)
Counting from LMP (12 April 2026) to today (11 July 2026):
| Period | Count |
|---|---|
| 12 April → 12 July | 13 weeks exactly |
| But today is 11 July | 13 weeks - 1 day |
| POG = 12 weeks + 6 days |
POG = 12 weeks and 6 days (approaching the end of the first trimester)
Quick Summary
| Parameter | Result |
|---|---|
| LMP | 12 April 2026 |
| EDD (Naegele's) | 19 January 2027 |
| POG (today, 11 Jul 2026) | 12 weeks 6 days |
| Trimester | 1st Trimester (ends at 13 weeks 6 days) |
Note: EDD calculated by Naegele's Rule assumes a regular 28-day cycle with ovulation on Day 14. Ultrasound dating (especially at 11-14 weeks) remains the gold standard for confirming EDD.
